3870 | The real problem of science is how to choose between possible explanations [Newton-Smith] |
Full Idea: Once we move beyond investigating correlations between observables the question of what does or should guide our choice between alternative explanatory accounts becomes problematic. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], IX.2) |
3853 | For science to be rational, we must explain scientific change rationally [Newton-Smith] |
Full Idea: We are only justified in regarding scientific practice as the very paradigm of rationality if we can justify the claim that scientific change is rationally explicable. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], I.2) |
3859 | We do not wish merely to predict, we also want to explain [Newton-Smith] |
Full Idea: We do not wish merely to predict, we also want to explain. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], II.3) |
3854 | Positivists hold that theoretical terms change, but observation terms don't [Newton-Smith] |
Full Idea: For positivists it was taken that while theory change meant change in the meaning of theoretical terms, the meaning of observational terms was invariant under theory change. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], I.4) |
3855 | Critics attack positivist division between theory and observation [Newton-Smith] |
Full Idea: The critics of positivism attacked the conception of a dichotomy between theory and observation. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], I.4) |
3861 | Theories generate infinite truths and falsehoods, so they cannot be used to assess probability [Newton-Smith] |
Full Idea: We cannot explicate a useful notion of verisimilitude in terms of the number of truths and the number of falsehoods generated by a theory, because they are infinite. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], III.4) |
3869 | More truthful theories have greater predictive power [Newton-Smith] |
Full Idea: If a theory is a better approximation to the truth, then it is likely that it will have greater predictive power. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], VIII.8) |
17743 | De Morgan introduced a 'universe of discourse', to replace Boole's universe of 'all things' [De Morgan, by Walicki] |
Full Idea: In 1846 De Morgan introduced the enormously influential notion of a possibly arbitrary and stipulated 'universe of discourse'. It replaced Boole's original - and metaphysically a bit suspect - universe of 'all things'. | |
From: report of Augustus De Morgan (works [1846]) by Michal Walicki - Introduction to Mathematical Logic History D.1.1 | |
A reaction: This not only brings formal logic under control, but also reflects normal talk, because there is always an explicit or implicit domain of discourse when we talk. Of virtually any conversation, you can say what it is 'about'. |
3867 | De re necessity arises from the way the world is [Newton-Smith] |
Full Idea: A necessary truth is 'de re' if its necessity arises from the way the world is. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], VII.6) |
3872 | We must assess the truth of beliefs in identifying them [Newton-Smith] |
Full Idea: We cannot determine what someone's beliefs are independently of assessing to some extent the truth or falsity of the beliefs. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], X.4) |
3857 | Defeat relativism by emphasising truth and reference, not meaning [Newton-Smith] |
Full Idea: The challenge of incommensurability can be met once it is realised that in comparing theories the notions of truth and reference are more important than that of meaning. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], I.6) |
3858 | A full understanding of 'yellow' involves some theory [Newton-Smith] |
Full Idea: A full grasp of the concept '…is yellow' involves coming to accept as true bits of theory; that is, generalisations involving the term 'yellow'. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], II.2) |
3863 | The anomaly of Uranus didn't destroy Newton's mechanics - it led to Neptune's discovery [Newton-Smith] |
Full Idea: When scientists observed the motion of Uranus, they did not give up on Newtonian mechanics. Instead they posited the existence of Neptune. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], III.9) |
3864 | Anomalies are judged against rival theories, and support for the current theory [Newton-Smith] |
Full Idea: Whether to reject an anomaly has to be decided on the basis of the availability of a rival theory, and on the basis of the positive evidence for the theory in question. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], III.9) |
3862 | All theories contain anomalies, and so are falsified! [Newton-Smith] |
Full Idea: According to Feyerabend all theories are born falsified, because no theory has ever been totally free of anomalies. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], III.9) |
3865 | Why should it matter whether or not a theory is scientific? [Newton-Smith] |
Full Idea: Why should it be so important to distinguish between theories that are scientific and those that are not? | |
From: W.H. Newton-Smith (The Rationality of Science [1981], IV.3) |
3866 | If theories are really incommensurable, we could believe them all [Newton-Smith] |
Full Idea: If theories are genuinely incommensurable why should I be faced with the problem of choosing between them? Why not believe them all? | |
From: W.H. Newton-Smith (The Rationality of Science [1981], VII.1) |
3871 | Explaining an action is showing that it is rational [Newton-Smith] |
Full Idea: To explain an action as an action is to show that it is rational. | |
From: W.H. Newton-Smith (The Rationality of Science [1981], X.2) |
23125 | Most good social changes are incremental, rather than revolutionary [Gopnik] |
Full Idea: More permanent positive social change is made incrementally rather than by revolutionary transformation. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 1) | |
A reaction: This is the standard liberal response to revolution. Revolutionaries obviously consider such a claim to be very naïve, and a failure to grasp how deep the changes need to go. |
23126 | Conservatives often want peace, prosperity and tolerance, but not social fairness [Gopnik] |
Full Idea: Many conservatives want their world to be peaceful, properous, and pluralist, just as liberals do, but they don't particularly care that it be fair. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 1) | |
A reaction: Every conservative will have a sense of what is fair (such as appropriate punishments, and keeping of contracts), but they are more inclined to think that fairness must be fought for by individuals, not imposed by governments. |
23132 | Conservatives believe obedience and rank are essential to social order [Gopnik] |
Full Idea: The idea that the appearance of submission and obedience and rank are essential to order is at the heart of the conservative ideal. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 2) | |
A reaction: [He has just quoted Edmund Burke writing of Marie Antoinette] I once heard Richard Hare say that he thought social order would be best modelled on the army. A colleague once told me that obedience is a prime duty of a school teacher. |
23128 | The opposite of liberalism is dogmatism [Gopnik] |
Full Idea: The opposite of liberalism is not conservatism but dogmatism. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 1) | |
A reaction: Nice. It pinpoints the liberal opposition to both extremes of normal politics. It might make anarchists their allies, though! |
23142 | People are fallible, so liberalism tries to distribute power [Gopnik] |
Full Idea: Liberalism makes the idea of fallibility into a political practice by trying not to have too much power concentrated in one place or part of the system. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: There is a potential inefficiency and failure to focus on key goals implicit in this aim. It may be a good idea for a peacetime democracy, but a terrible idea for a wartime army. To stop corruption, don't let anyone do anything? |
23143 | Liberals have tried very hard to build a conscience into their institutions [Gopnik] |
Full Idea: What liberalism can say on its own behalf is that no system of power in human history has tried harder to insert a corrective conscience into its institutions. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: What we are learning in recent years is that wonderful liberal institutions can be quietly eroded by the forces of darkness, once those forces have sufficient control of the media to hide what they are doing. The 'rule of law' is wobbling. |
23141 | Left-wingers are inconsistent in their essentialist descriptions of social groups [Gopnik] |
Full Idea: A criticism of the left is that it is essentialist at some moments, and wildly anti-essentialist at others. We can call this opportunistic essentialism. Gender is fluid - except for transgender kids. Race is a construction - except for white races. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: [compressed] Interesting. Gopnik's solution seems to be to abandon all social essentialism as wicked. In this context he is probably right, but I am firmly committed to the idea that many entities in the world have essential natures. 'Bourgeois'. |
23124 | Liberal community is not blood ties or tradition, but shared choices, and sympathy for the losers [Gopnik] |
Full Idea: The liberal idea of community is not one, as it is for many conservatives, of blood ties or traditional authority. It rest on the idea of shared choices …including even a sense of sympathy for those caught on the losing side of the argument. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 1) | |
A reaction: The key point is that most liberals (other than extreme libertarians) have a strong sense of community, contrary to the standard criticisms offered by communitarians. |
23127 | Liberal community includes flight from the family, into energetic reforming groups [Gopnik] |
Full Idea: Where conservatives believe in the renewal of traditional community, liberals believe as well in the flight from family and tradition into new kinds of communal order. …It is an idea of assembling confidence and energies for reform. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 1) | |
A reaction: He cites Greenwich Village as an example. This suggests that his vision is a little narrow. His communities are for radicals who flee to join like minds in big cities. Politics must care about community for those left behind. Pubs, sport and pets. |
23138 | Modern left-wingers criticise liberalism's control of culture [Gopnik] |
Full Idea: Most left-wing critiques of liberalism now turn more often on its cultural power and its cultural illusions. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: As opposed to older Marxists critiques of the exploitation of workers. This is certainly fertile ground for interesting studies of our culture. It is very hard to grasp the influence had by the endless stories we expose ourselves to. |
23129 | Right-wingers attack liberal faith in reason, left-wingers attack its faith in reform [Gopnik] |
Full Idea: The right-wing critique of liberalism is largely an attack on its overreliance on reason; the left-wing one, mostly an attack on its false faith in reform. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 2) | |
A reaction: I doubt whether sensible liberals do rely too much on reason, though they do rely of scientific evidence (after peer review!). No one can doubt that lots of reforms have occurred, so it must be frustration with the very slow process. |
23133 | Cosmopolitan liberals lack national loyalty, and welcome excessive immigration [Gopnik] |
Full Idea: Critics say liberal cosmopolitanism is indifference to national loyalty, making them easily contemplate going elsewhere and, worse still, welcoming in the world through unsifted immigration. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 2) | |
A reaction: There is certainly some truth in this. Not all liberals are so cosmopolitan, though. It is interesting to observe whether people who retire stay in their old community or move to somewhere quite new. |
23139 | Liberalism's attempt to be neutral and colour-blind erases cultural identities [Gopnik] |
Full Idea: The 'colour-blind' universe of 'neutral' liberalism is actually an attempt to erase cultural identity and history. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: This is the modern critique of liberalism [centred on the Intersectionality of Bell Hooks or Kimberlé Crenshaw], which analyses alienated minorities, and their emphasis on their difference in response. It can lead to 'identity politics'. |
23135 | Classic Marxists see liberalism as the ideology of the bourgeoisie [Gopnik] |
Full Idea: The classic Marxist account shows liberalism as merely the ideology of the bourgeoisie. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: The word 'merely' does an awful lot of work in philosohy! I suspect that 'bourgeoisie' is self-defining here - as the believers in liberalism - given that lots of Marxists emerge from the middle classes. |
23140 | Environmental disasters result not from capitalism, but from a general drive for growth [Gopnik] |
Full Idea: It is the drive for growth, not capitalism in particular, that makes environmental disasters happen. Those caused by the command economics of Eastern Europe were far greater than even the worst known in Western Europe. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: So the next question is whether you can have capitalism without a drive for growth. I would have thought not, given the role recycled profit plays in driving capitalism. Command economies are more easily swept away. |
23130 | Popular imperialism gives the poor the belief that their acts have world historical meaning [Gopnik] |
Full Idea: Popular imperialism is the cosmopolitanism of the poor, the lever by which the small and impotent come to believe that their acts have world historical meaning. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 2) | |
A reaction: It is not only the poor who like imperialism. The focus of this popular attitude is the armed forces, and especially the army, where personal bravery is most obvious. The army gets strong support, no matter how dubious are its activities. |
23131 | Patriots love their place, but nationalists have a paranoid ethnic hostility [Gopnik] |
Full Idea: The patriot loves his place and its cheeses; …the nationalist has not particular affection for the place, but employs his obsessive sense of encirclement and grievance on behalf of acts of ethnic vengeance. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 2) | |
A reaction: 'Vengeance' seems a bit strong. John Le Carré said nationalists are distinguished by the need to have enemies. Russia is particularly obsessed with 'encirclement'. |
23136 | Liberal free speech is actually paid speech [Gopnik] |
Full Idea: What liberals call free speech or a free press is invariably paid speech. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: He give this as the left-wing view of liberalism. The much-hated social media are a substantial breech in this tendency. Sales of newspapers are declining everywhere, so the battle is for television channels. |
23134 | A 'free' society implies a free market, which always produces predatory capitalism and inequalities [Gopnik] |
Full Idea: 'Free societies', as a matter of practical fact, always mean free-market societies - and free markets will never sponsor more than predatory capitalism. Inequalities always emerge. | |
From: Adam Gopnik (A Thousand Small Sanities [2019], 3) | |
A reaction: This is part of his account of left-wing objections to liberalism. The crux of the liberal view is a conviction that the worst of capitalism can be restrained. This began to look doubtful once huge multinational companies emerged. What to do? |
